T808/807 DC Power Supply Connection & Torque Settings
Warning:
Securing the DC Power Supply cable into the DC connector to provide a good electrical
connection is essential. Over time, the wires tend to compress in the DC connector re-
sulting in an increasingly poorer connection. Consequently, as high current is drawn,
the connector heats up increasing the resistance thereby causing still more heat until the
connector eventually burns up.

Although screws securing DC cables to the Power Supply terminals are tightened to the torque set-
tings given below prior to new system delivery, they must be re-tightened as part of the commis-
sioning process and re-tightening is also part of the regular maintenance schedule.

Prior to replacing a Power Supply module into an existing system, inspect the cable and re-terminate
the DC wires if the strands have previously been twisted together or show any sign of damage.

Cut the wire at the end of the insulation and then strip approximately .4 inch (10mm) of insula-
tion off the cable. DO NOT TWIST THE WIRE STRANDS. Insert the DC cable into the screw
terminal and tighten the screw to secure the cable as per the torque settings given below.
tion off the cable. DO NOT TWIST THE WIRE STRANDS. Insert the DC cable into the screw
terminal and tighten the screw to secure the cable as per the torque settings given below.
Torque Settings:
The manufacturer recommends torque setting all power supply terminal screws to:
•
0.5 to 0.6 Nm (or 4.5 to 5.3 In/lb or to .37 to .44 ft/lb)
Note: Dataradio uses a Sturtuvan Richmond 29-pieces adjustable torque screwdriver model
CAL36/4K.
After tightening, pull on the cable to check the cable is secured tightly into the screw terminal.
